Abstract: In a tower integrated by the heating and drying section and the cooling section, both sides of the heating and drying section housing are provided with an air inlet box and an air outlet box; the air inlet box is communicating with a heat exchanger and distribution pipes in the heating and drying section housing, the air outlet box is communicating with distribution pipes in the heating and drying section housing and a dust remover; both sides of the cooling section housing are provided with an air inlet box and an air outlet box; the air inlet box is communicating with a heat exchanger and distribution pipes in the cooling section housing; the air outlet box is communicating with distribution pipes in the cooling section housing and a dust remover. The integral device improves the heat exchange effect and preventing the polypropylene particles from aging.

Abstract: An apparatus for removing VOC in polypropylene by steaming process includes: a cyclone separator, used for separating polypropylene particles and entraining gas from an upstream pneumatic system; a preheating tower, communicating with a discharge hole of the cyclone separator, a first steam inlet being provided on a tower body of the preheating tower, and a tail gas outlet being provided on top of the preheating tower; and a devolatilization tower, communicating with a discharge hole of the preheating tower, a second steam inlet being provided on a tower body of the devolatilization tower, a steam outlet being provided on top of the tower, and the steam outlet being communicating with the first steam inlet.

Abstract: A method for drying high moisture, low calorific value lignite for a generating set and recovering water contained therein and an apparatus thereof mainly consist of a rotary steam tube dryer, a washing cooling tower, a coal mill, a first bag filter, a condenser, a weighing surge bunker, a water ring vacuum pump and so on. A drying system is integrated with a milling system, every dryer and the corresponding coal mill are disposed and are directly connected via a surge bunker, thereby not only saving the heat lost during the transportation of pulverized coal, but also omitting a long-distance transportation from a conventional drying system to a conventional milling system, effectively avoiding such phenomena as dust pollution, waste and spontaneous combustion during transportation and transshipment, simplifying the coal preparation system employed in the front-end process of drying.

Abstract: The present invention relates to a method for drying high moisture, low calorific value lignite for a generating set and recovering water contained therein and an apparatus thereof, which mainly consisting of a rotary steam tube dryer, a washing cooling tower, a coal mill, a 1st bag filter I, a condenser, a weighing surge bunker, a water ring vacuum pump and so on. In the present invention, a drying system is integrated with a milling system, every dryer and the corresponding coal mill are disposed and are directly connected via a surge bunker, thereby not only saving the heat lost during the transportation of pulverized coal, but also omitting a long-distance transportation from a conventional drying system to a conventional milling system, effectively avoiding such phenomena as dust pollution, waste and spontaneous combustion during transportation and transshipment, simplifying the coal preparation system employed in the front-end process of drying.

Abstract: A dehumidifying tower having a washing section, a flash-distilling section, and a condensing section. In the washing section, exhaust gas is washed with a cooling liquid to remove at least a portion of solid dust entrained in the exhaust gas, cool the exhaust gas, and condense at least a portion of moisture in the exhaust gas into liquid. The flash-distilling section flash-distills the cooling liquid used in the washing section to produce a cooled cooling liquid and a cooling liquid vapor. Cooling liquid produced by flash-distillation enters the washing section. The flash-distilling section is in gas-phase isolation from the washing section. The condensing section condenses the cooling liquid vapor produced by flash-distillation. The condensing section is configured to be in gas-phase communication with and liquid-phase isolation from the flash-distilling section, and be in both gas-phase and liquid-phase isolation from the washing section.

Abstract: The invention relates to an exhaust gas separating tower, comprising a washing section, a flash-distilling section above the washing section, and a liquid seal means between the flash flash-distilling section and the washing section. The washing section is configured for washing exhaust gas entering the tower with a cooling liquid to at least partially remove solid dust entrained in the exhaust gas, cool the exhaust gas, and condense at least a portion of moisture in the exhaust gas into liquid. The flash-distilling section is configured for flash-distilling the cooling liquid from the washing section to produce a cooled cooling liquid and a cooling liquid vapor. The liquid seal means is configured so that the cooling liquid produced by flash-distillation can enter the washing section through the liquid seal means while the flash-distilling section is in gas-phase isolation from the washing section, wherein a pressure in the flash-distilling section is lower than that in the washing section.
